Why did those spectacular city walls disappear in the late Qing Dynasty?

In ancient China, where there were cities, there were walls. High and thick city walls are an important guarantee to protect the safety of urban residents.

However, at present, only a few cities in China still have some city walls, so where have all the historical city walls gone? Let's take a look at some old photos of the late Qing Dynasty and miss the city walls at that time.

0 1: 1860 The wall of Ding 'anmen in Beijing occupied by British and French allied forces in the Second Opium War.

02: 1897- 1898 JIAOZHOU, Shandong Province, occupied by the German imperial navy. The picture shows the scene outside the walls of JIAOZHOU.

03: 1900 the scene outside the wall of Beijing Dongbianmen. Looking at that tower, is there an impulse to look up?

04: 1909 high-definition old photos of Fengtian. The picture shows the photos outside the east gate of Fengtian. At that time, the tower was in ruins.

The picture shows Fengtian, inside the Dongcheng wall: People's houses are close to the wall, which means they think it is safe as long as there is a wall!

05: 1909 The photos outside Xuanhua City Wall show that the wall behind it looks so difficult to conquer.

Today, many city walls no longer exist.

I asked some old people with questions, and the answer was: whether it is War of Resistance against Japanese Aggression or the war of liberation, the tall city walls are the most difficult to conquer. It's too expensive to conquer a city with walls!

At the beginning of the liberation war, the prediction of repeated fighting was relatively large. In order to reduce the enemy's reoccupation and defense of the city and cause great losses to our army, the PLA generally organizes the military and civilians to tear down the city walls after capturing a city. To prevent the wall from being used by the enemy again after the counterattack.

There are five city walls in the text. Who else is there now? What have you been to? Leave a message about your feelings!
